Let (-1)n-1un be an alternating series. The Alternating Series Test (AST) has 3 conditions to check for convergence. They are: O (1) un can alternate. (2) un≥ Un+1. (3) lim un=0. n→∞ O (1) un≥ 0 for all n. (2) Un≥ Un+1 for n large enough. (3) lim un=0. n18 O (1) un≥ 0 for all n. (2) uns Un+1 for n large enough. (3) lim un=0. n18 O (1) un≥ 0 for all n. (2) un≥ Un+1 for n large enough. (3) lim un 0. n-m
